Dawb crystalline hmoov; me ntsis soluble hauv dej, me ntsis soluble hauv cawv thiab aether, soluble hauv dej kub, cawv kub thiab sodium hydroxide kua.
Allantoin yog ib hom hmoov ua los ntawm cov khoom siv, uas ntws tau yooj yim thiab siv dav hauv kev kho kom zoo nkauj, kev kho mob tawv nqaij thiab kev tsim tshuaj vim nws cov yam ntxwv ua rau so thiab tiv thaiv kev khaus. Allantoin muaj cov nyhuv ua rau noo noo thiab keratolytic, ua rau cov dej ntau ntxiv rau hauv cov khoom sab nraud thiab ua rau cov tawv nqaij tuag ploj mus, ua rau daim tawv nqaij du thiab du; txhawb kev loj hlob ntawm cov hlwb thiab kho qhov txhab; thiab ua rau so, tiv thaiv kev khaus, thiab tiv thaiv daim tawv nqaij los ntawm kev tsim cov tshuaj sib xyaw nrog cov tshuaj khaus thiab cov neeg sawv cev ua rau khaus. Allantoin txhawb kev tsim cov nqaij mos zoo li qub txawm tias muaj qhov tsawg tsawg.
Txawm hais tias allantoin muaj nyob rau hauv cov tshuaj ntsuab ntawm cov nroj tsuag comfrey, nws feem ntau yog synthesized los ua kom tau raws li qhov xav tau thoob ntiaj teb.
